It helps resolve lane markings, signs, signals, barriers, and static object assets from source map data. **Install:** ```bash npx degit https://github.com/matlab/matlab-agentic-toolkit/tree/main/skills-catalog/automotive/roadrunner-asset-mapping ~/.claude/skills/roadrunner-asset-mapping ``` ## README # RoadRunner Asset Mapping Consolidated lookup tables for mapping source map format elements to RoadRunner project asset paths. All paths are relative to the project `Assets/` folder. ## When to Use - Resolving lane marking subtypes to RoadRunner `.rrlms` asset paths - Mapping sign codes (US MUTCD, German StVO, Japanese) to sign asset SVGs - Looking up barrier/extrusion asset paths for fence, guard rail, jersey barrier, wall - Finding prop/static object asset paths for placement in RRHD - Determining region-specific sign paths based on geoReference coordinates - Assigning lane type enums from source format lane classifications ## When NOT to Use - Building RRHD objects from scratch — use `roadrunner-rrhd-authoring` - Performing the full Lanelet2 conversion pipeline — use `roadrunner-convert-lanelet2-to-rrhd` - Importing maps into RoadRunner — use `roadrunner-import-scene` ## Key Rules - **All asset paths start with `Assets/`** — always prefix when constructing `RelativeAssetPath` objects. - **Extension matters.** `.rrlms` = lane marking style, `.rrcws` = crosswalk style, `.rrpms` = polygon marking style, `.svg_rrx` = sign. Using wrong extension causes "Asset file is missing" on import. - **Signs use `.svg_rrx` extension** (NOT `.svg`). The `.svg` paths in XML configs are internal references only. - **Sign naming: descriptive English names** with region suffix (e.g., `Stop_JP_01.svg_rrx`, `MaxSpeedLimit_30_DE.svg_rrx`). The old `Sign_.svg` naming is obsolete. - **Region detection from geoReference.** Use lat/lon to determine Japan/Germany/US for sign and marking paths. - **Runtime asset discovery is MANDATORY for signs.** Asset names vary by version — always verify file exists before assigning. ## Source Data Asset mappings are derived from the official RoadRunner project configuration XMLs: - `DefaultAssets.xml` — default materials and markings - `ApolloAssetData.xml` — Apollo/Baidu HD Map format - `OpenDriveAssetData.xml` — OpenDRIVE format - `HEREAssetData_NA.xml` / `HEREAssetData_WE.xml` — HERE HD Map (NA/EU) - `TomTomAssetData.xml` — TomTom HD Map format These XML files are located in the RoadRunner project's configuration directory (typically `/Configuration/`). ## Lane Markings See [references/laneMarkings.md](references/laneMarkings.md) for full mapping table. **Key patterns:** - All marking assets are in `Assets/Markings/` with `.rrlms` extension - Markings are keyed by **type** (solid/dashed/double) + **color** (white/yellow) - Default road center marking: `SolidDoubleYellow.rrlms` - Default outer boundary: `SolidSingleWhite.rrlms` ## Signs See [references/signs.md](references/signs.md) for full mapping table. **CRITICAL: Asset File Extension** - RoadRunner sign assets use **`.svg_rrx`** extension on disk (NOT `.svg`) - The `.svg` paths in project XML configs are internal references only - **Always use `.svg_rrx` in `RelativeAssetPath` objects** — using `.svg` causes "Could not find asset" errors **MANDATORY: Runtime Asset Discovery** - Sign asset names vary by RoadRunner version and installed asset libraries - **Always verify at runtime** that the target asset exists before assigning it - Use `dir(fullfile(projFolder, 'Assets', 'Signs', region, category, '*.svg_rrx'))` to discover available signs **Key patterns:** - US signs: `Assets/Signs/US/Regulatory Signs/` or `Assets/Signs/US/Warning Signs/` - German signs: `Assets/Signs/Germany/Regulatory Signs/` - Japan signs: `Assets/Signs/Japan/Regulatory Signs/` or `Assets/Signs/Japan/Warning Signs/` - Sign geometry uses `GeoOrientedBoundingBox` (Center + Dimension + GeoOrientation) **Naming convention:** Signs use **descriptive English names** with region suffix: - Pattern: `_.svg_rrx` (e.g., `Stop_JP_01.svg_rrx`, `MaxSpeedLimit_30_JP.svg_rrx`) - The old `Sign_.svg` naming is **obsolete** — files do NOT exist on disk **Region detection from geoReference:** ```matlab lat = geoRef(1); lon = geoRef(2); if lat >= 24 && lat <= 46 && lon >= 122 && lon <= 154 region = "Japan"; elseif lat >= 35 && lat <= 72 && lon >= -10 && lon <= 25 region = "Germany"; else region = "US"; end ``` **Region-specific sign paths (verified R2026a with RoadRunner_Asset_Library):** | Sign | Japan | US | Germany | |---|---|---|---| | Stop | `Signs/Japan/Regulatory Signs/Stop_JP_01.svg_rrx` | `Signs/US/Stop_US.svg_rrx` | `Signs/Germany/Regulatory Signs/Stop_DE.svg_rrx` | | Yield | — | `Signs/US/Yield_US.svg_rrx` | `Signs/Germany/Regulatory Signs/Yield_DE.svg_rrx` | | Speed N | `Signs/Japan/Regulatory Signs/MaxSpeedLimit__JP.svg_rrx` | `Signs/US/Regulatory Signs/MaxSpeedLimit__US.svg_rrx` | `Signs/Germany/Regulatory Signs/MaxSpeedLimit__DE.svg_rrx` | | Fallback | `Signs/Japan/Regulatory Signs/SlowDown_JP_01.svg_rrx` | `Signs/US/White_Blank_US.svg_rrx` | `Signs/Germany/Warning Signs/Danger_DE.svg_rrx` | ## Signals (Traffic Lights) | Configuration | Asset Path | |---|---| | 3-light vertical (post) | `Props/Signals/Signal_3Light_Post01.fbx` | | 3-light vertical (bare) | `Props/Signals/Signal_3Light_Bare01.fbx_rrx` | **Authoring vs Import limitation:** You CAN author `SignalType` objects (add to `rrMap.SignalTypes`) and `Signal` instances (add to `rrMap.Signals`) in MATLAB and write the map to `.rrhd` — signal data IS written to the file and survives read/write cycles. However, RoadRunner **silently ignores** signals when importing `.rrhd` maps — signals will not appear in the RoadRunner scene after import. Show the asset paths and authoring code, but warn the user about this import limitation. ## Barriers & Extrusions See [references/barriers.md](references/barriers.md) for full mapping table. **Key patterns:** - All extrusions in `Assets/Extrusions/` with `.rrext` or `.rrext.rrmeta` extension - Barriers use `roadrunner.hdmap.BarrierType` with `ExtrusionPath` ## Props & Static Objects See [references/staticObjects.md](references/staticObjects.md) for full mapping table. **Key patterns:** - Props in `Assets/Props/` subdirectories (Trees, Signals, TrafficControl, etc.) - Static objects use `roadrunner.hdmap.StaticObjectType` with `AssetPath` - Objects use `GeoOrientedBoundingBox` for placement ## Lane Types See [references/laneTypes.md](references/laneTypes.md) for full mapping table. ## Crosswalks & Curve Markings **Extension rules** (commonly confused): - `.rrcws` = crosswalk style (only for actual crosswalks) - `.rrlms` = lane marking style (stop lines, bike markings, zig-zag) - `.rrpms` = polygon marking style (striped regions, chevrons) - `.rrcws_rrx` / `.rrlms_rrx` = region-specific variants (Japan, Germany, etc.) **Base assets (universal):** | Type | Asset Path | Extension | |---|---|---| | Simple crosswalk | `Markings/SimpleCrosswalk.rrcws` | `.rrcws` | | Continental crosswalk | `Markings/ContinentalCrosswalk.rrcws` | `.rrcws` | | Ladder crosswalk | `Markings/LadderCrosswalk.rrcws` | `.rrcws` | | Stop line | `Markings/StopLine.rrlms` | `.rrlms` | | Striped region | `Markings/StripedRegion.rrpms` | `.rrpms` | **Japan-specific markings (`.rrlms_rrx` / `.rrcws_rrx`):** | Type | Asset Path | |---|---| | Stop line | `Markings/Japan/StopLine_JP.rrlms_rrx` | | Crosswalk | `Markings/Japan/SimpleCrosswalk_JP.rrcws_rrx` | | Solid single white | `Markings/Japan/SolidSingleWhite_JP.rrlms_rrx` | | Dashed single white | `Markings/Japan/DashedSingleWhite_JP.rrlms_rrx` | | Solid double white | `Markings/Japan/SolidDoubleWhite_JP.rrlms_rrx` | | Solid double yellow | `Markings/Japan/SolidDoubleYellow_JP.rrlms_rrx` | **Germany-specific markings:** | Type | Asset Path | |---|---| | Stop line | `Markings/Germany/StopLine_DE.rrlms_rrx` | | Crosswalk | `Markings/Germany/SimpleCrosswalk_DE.rrcws_rrx` | **Region selection:** Use base (non-regional) assets as default. Use regional variants when the map's geoReference indicates a specific region AND the regional asset exists in the project. ## Stencils (Road Surface Markings) | Type | Asset Path | |---|---| | Arrow left | `Assets/Stencils/Stencil_ArrowType4L.svg` | | Arrow right | `Assets/Stencils/Stencil_ArrowType4R.svg` | | STOP text | `Assets/Stencils/Stencil_STOP.svg` | ## Materials | Purpose | Asset Path | |---|---| | Road surface | `Assets/Materials/Asphalt1.rrmtl` | | Sidewalk / concrete | `Assets/Materials/Concrete1.rrmtl` | | Ground / grass | `Assets/Materials/Grass1.rrmtl` | ## Default Assets These are the project-wide defaults (from `DefaultAssets.xml`): | Name | Path | |---|---| | Island Curb Material | `Assets/Materials/Concrete1.rrmtl` | | Blank Sign | `Assets/Signs/US/White_Blank_US.svg_rrx` | | Blank Warning Sign | `Assets/Signs/US/Yellow_Blank_US.svg_rrx` | | Surface Material | `Assets/Materials/Grass1.rrmtl` | | Crosswalk | `Assets/Markings/SimpleCrosswalk.rrcws` | | Stop Line | `Assets/Markings/StopLine.rrlms` | | Parking Space Marking | `Assets/Markings/SolidSingleWhite.rrlms` | | Road Surface Material | `Assets/Materials/Asphalt1.rrmtl` | | Road Center Marking | `Assets/Markings/SolidDoubleYellow.rrlms` | | Dashed Road Marking | `Assets/Markings/DashedSingleWhite.rrlms` | | Road Outer Boundary | `Assets/Markings/SolidSingleWhite.rrlms` | | Road Inner Boundary | `Assets/Markings/SolidSingleYellow.rrlms` | | One Way Passing | `Assets/Markings/DashedSolidYellow.rrlms` | | Vehicle | `Assets/Vehicles/Sedan.fbx` | ## Usage Pattern (MATLAB) ```matlab % Example: resolve marking asset path function assetPath = resolveMarkingAsset(type, color) % type: "solid", "dashed", "solid_solid", etc. % color: "white", "yellow" (default: white) if nargin < 2, color = "white"; end % Use lookup from references/laneMarkings.md end ``` All asset paths are prefixed with `Assets/` when used in RRHD `RelativeAssetPath` objects. ## Conventions - All marking assets: `Assets/Markings/.` — extension determines type (`.rrlms`, `.rrcws`, `.rrpms`) - Regional marking variants: `Assets/Markings//_._rrx` (e.g., `_JP.rrlms_rrx`) - All sign assets: `Assets/Signs///_.svg_rrx` (NOT `.svg`) - All extrusion assets: `Assets/Extrusions/.rrext` (or `.rrext.rrmeta`) - All prop assets: `Assets/Props//.fbx` (or `.fbx_rrx`) - Use `RelativeAssetPath(AssetPath="...")` for RRHD construction (Name=Value syntax) - Default road center: `SolidDoubleYellow.rrlms`; default outer boundary: `SolidSingleWhite.rrlms` - **Always verify asset exists at runtime** before assigning — paths vary by version and installed libraries ---- Copyright 2026 The MathWorks, Inc.
